1. p- K KL m+

2. m+ component, ME m+ component, LE Difference

3. So carried out idea… Nubar-PID performance on L100200

4. data and MC L010185 L100200 data rw-MC data rw-MC data (L100200-L010185) rw-MC (L100200-L010185)

5. n (no m+), LE n (no m+), ME L010185 and L100200 MC (reweighed) ratio diff

6. 1st try: fit the ME-LE data with the following function: Simple chi-squared used for the fit: where:

7. 1st check: Fit for (ME-LE)MCafter correcting for ME,LE differences with the MC: ME-LE, no m+ (MC) (ME-LE)MC Fit  parME and parLE indeed converge at 1.0

8. 2nd check: Fit for (ME-LE)MCassuming no ME,LE differences besides m+: (ME-LE)MC Fit Fit values: parLE = 0.728±0.591 parME= 1.303±0.297

9. Now fit for (ME-LE)DATAassuming no ME,LE differences besides m+: (ME-LE)DATA Fit Fit values: parLE = 2.623±0.847 parME= 0.703±0.436

10. Fit (ME-LE)MC again with less bins: (ME-LE)MC Fit Fit values: parLE = 0.195±0.587 parME= 1.015±0.290

11. Fit (ME-LE)DATA again with less bins: (ME-LE)MC Fit Fit values: parLE = 1.793±0.861 parME= 0.477±0.431
